An update that solves 15 vulnerabilities and has four fixes is now available.

Description:

This update for qemu fixes several issues.

These security issues were fixed:

- CVE-2017-5898: The CCID Card device emulator support was vulnerable to an integer overflow flaw allowing a privileged user to crash the Qemu process on the host resulting in DoS (bsc#1023907). - CVE-2017-5857: The Virtio GPU Device emulator support was vulnerable to a host memory leakage issue allowing a guest user to leak host memory resulting in DoS (bsc#1023073). - CVE-2017-2620: In CIRRUS_BLTMODE_MEMSYSSRC mode the bitblit copy routine cirrus_bitblt_cputovideo failed to check the memory region, allowing for an out-of-bounds write that allows for privilege escalation (bsc#1024972) - CVE-2017-2615: An error in the bitblt copy operation could have allowed a malicious guest administrator to cause an out of bounds memory access, possibly leading to information disclosure or privilege escalation (bsc#1023004) - CVE-2017-5856: The MegaRAID SAS 8708EM2 Host Bus Adapter emulation support was vulnerable to a memory leakage issue allowing a privileged user to leak host memory resulting in DoS (bsc#1023053) - CVE-2016-9921: The Cirrus CLGD 54xx VGA Emulator support was vulnerable to a divide by zero issue while copying VGA data. A privileged user inside guest could have used this flaw to crash the process instance on the host, resulting in DoS (bsc#1014702) - CVE-2016-9922: The Cirrus CLGD 54xx VGA Emulator support was vulnerable to a divide by zero issue while copying VGA data. A privileged user inside guest could have used this flaw to crash the process instance on the host, resulting in DoS (bsc#1014702) - CVE-2016-10029: The Virtio GPU Device emulator support was vulnerable to an OOB read issue allowing a guest user to crash the Qemu process instance resulting in Dos (bsc#1017081). - CVE-2016-10028: The Virtio GPU Device emulator support was vulnerable to an out of bounds memory access issue allowing a guest user to crash the Qemu process instance on a host, resulting in DoS (bsc#1017084). - CVE-2016-10155: The virtual hardware watchdog 'wdt_i6300esb' was vulnerable to a memory leakage issue allowing a privileged user to cause a DoS and/or potentially crash the Qemu process on the host (bsc#1021129) - CVE-2017-5552: The Virtio GPU Device emulator support was vulnerable to a memory leakage issue allowing a guest user to leak host memory resulting in DoS (bsc#1021195). - CVE-2017-5578: The Virtio GPU Device emulator support was vulnerable to a memory leakage issue allowing a guest user to leak host memory resulting in DoS (bsc#1021481). - CVE-2017-5526: The ES1370 audio device emulation support was vulnerable to a memory leakage issue allowing a privileged user inside the guest to cause a DoS and/or potentially crash the Qemu process on the host (bsc#1020589). - CVE-2017-5525: The ac97 audio device emulation support was vulnerable to a memory leakage issue allowing a privileged user inside the guest to cause a DoS and/or potentially crash the Qemu process on the host (bsc#1020491). - CVE-2017-5667: The SDHCI device emulation support was vulnerable to an OOB heap access issue allowing a privileged user inside the guest to crash the Qemu process resulting in DoS or potentially execute arbitrary code with privileges of the Qemu process on the host (bsc#1022541). - CVE-2017-5898: The CCID Card device emulator support was vulnerable to an integer overflow allowing a privileged user inside the guest to crash the Qemu process resulting in DoS (bnc#1023907)
